Tuple Methods

Indexing

t = (1, 2, 3, 4)
print(t[1])  # Output: 2

Slicing

t = (1, 2, 3, 4, 5)
print(t[1:3])  # Output: (2, 3)

Count

t = (1, 2, 3, 1, 2, 1)
print(t.count(1))  # Output: 3

Index

t = (1, 2, 3, 4, 2)
print(t.index(2))  # Output: 1

Length

t = (1, 2, 3, 4)
print(len(t))  # Output: 4

Concatenation

t1 = (1, 2)
t2 = (3, 4)
print(t1 + t2)  # Output: (1, 2, 3, 4)

Repetition

t = (1, 2)
print(t * 3)  # Output: (1, 2, 1, 2, 1, 2)

Membership

t = (1, 2, 3, 4)
print(2 in t)  # Output: True
print(5 in t)  # Output: False

Iteration

t = (1, 2, 3)
for item in t:
    print(item)
# Output:
# 1
# 2
# 3

Unpacking

t = (1, 2, 3)
a, b, c = t
print(a, b, c)  # Output: 1 2 3
